Working Principle of Electromagnet. The working principle of electromagnets depends on the relationship between electric currents and magnetic fields. When an electric current flows through a conductor, for example, a wire, it produces a magnetic field around it. By coiling the wire, the resulting magnetic field is strengthened.
Fig. 1 is a schematic diagram of the temperature regulation principle of an electric iron. The main components of the temperature regulating circuit of the electric iron are bimetallic sheets. When the electric iron works, the dynamic and static contacts are contacted, and the electric heating components are electrified and heated.
The working of an electric iron is very simple – it draws electricity from the mains and heats a coil inside. This heat is then transferred to the bottom plate, which is pressed against the clothing to remove wrinkles.
Working principle of transformer. ... Working of electrical transformer. Consider an iron core with two sets of windings on both of its limbs, as shown in the figure. When we connect the primary winding to a source of AC supply, the current flowing through the coil produces a magnetic field around it. This flux links with the iron core, and the ...
